+.SH DESCRIPTION
+.I curses
+provides applications the ability to write the contents of the screen
+to a file and read them back.
+To read/write a window
+(rather than the whole screen)
+from/to a file,
+use \fB\%getwin\fP(3X) and
+\fB\%putwin\fP(3X),
+respectively.
+.SS scr_dump
+\fB\%scr_dump\fP writes to
+.I filename
+the contents of the virtual screen;
+see \fB\%curscr\fP(3X).
+.SS scr_restore
+\fB\%scr_restore\fP updates the virtual screen to contain the contents
+of
+.I filename
+(if it was validly written with \fB\%scr_dump\fP).
+No refresh is performed;
+after performing any further desired updates,
+call \fB\%doupdate\fP(3X) or similar.
+.SS scr_init
+\fB\%scr_init\fP reads
+.IR filename ,
+using it to initialize
+.I curses
+data structures describing the state of the terminal screen.
+If these data are valid,
+.I curses
+bases its next update of the screen on this information rather than
+clearing it and starting from scratch.
